When playin with Direct3D driver, i got game speed reduced, although i still have 70 Frames per Second.
When i move arround a dynamic (or static) light, the game seems to run slowly, but the frames per second does not went down.
If i turn on FRAPS, and start to record a game video, the game returns to it's normal speed.
This does not occur when usin OpenGL Driver.
I will try to record a film of the game with my digital camera, so you can see the effect.
I will upload the video a bit later.
When using version 2.18
